a corporation of Delaware Application October 4, 1940, Serial No. 359.722 2 Claims. (01. 242125) This invention relates to a novel yarn support, and relates more particularly to a yarn support upon which a magazine wrap or transfer tail may be applied.

A magazine wrap or transfer tail, as commonly understood in the textile art, is a supplementary length comprising the inner end of the first portion of yarn wound on the yarn support. This magazine or transfer tail is so disposed as to be positively and safely secured during the winding and/or unwinding of the yarn package yet freely available for tying directly to the outer end of the yarn on another support for the purpose of smoothly effecting a continuous delivery of yarn without any stoppage or interruption. Our novel yarn support may be used in connection with winding means as more particularly shown, described and claimed in our co-pending application S. No. 353,534, filed on August 21, 1940, now Patent No. 2,261,239, issued Nov. 4, 1941.

An object of our invention is to provide a yarn support upon which a magazine wrap or transfer tail may be applied in a simple and eflicient manner.

- Another object of our invention is the provision of a yarn support upon which a magazine wrap or transfer tail may be applied and upon which the magazine wrap may be firmly and safely secured.

Another object of our invention is the provision of a yarn support upon which a magazine wrap or transfer tail may be applied firmly and safely secured while said yarn support is rotatably mounted and/or rotating during the normal initiation of the yarn winding operation thereon.

Other objects of our invention will appear from the following detailed description.

In the accompanying drawing, wherein certain preferred embodiments of our invention are shown,

Figure 1 is a plan view, partly in section, of one form of our novel yarn support showing the base flange containing grooves cut in the inner surface, which grooves serve as yarn guides in forming the magazin wrap or transfer tail,

Figure 2 is a fragmentary front elevational view of the embodiment shown in Figure 1 showing a peripheral groove in the base flange for receiving the yarn forming the transfer tail,

Figure 3 is a fragmentary view of the yarn support base flange, taken along the line 3-3 in Figure 1,

Figure 4 is a base flange,

Figure 5 is a fragmentary view of the yarn plan view of the bottom of the support base taken along the line 55 in Figure 4, and

Figure 6 is a plan view, partly in section, of another form of yarn support base showing a plurality of yarn guiding grooves cut in the inner surface of the base flange.

Like reference numerals indicate lik parts throughout the several views of the drawing.

Referring now to the drawing and more particularly to Figures 1 and 2, there is shown a yarn support having a base flang 'l which is attached to a barrel 8 for the reception of a spindle of the usual type for rotating the yarn support. The upper flange (not shown) of the yarn support is of the usual type'ancl is attached to the other end of the barrel 8. Yarn may be wound on the yarn support in any suitable manner as by means of a ring and traveler device. The traversing ring rail of the ring and traveler device may be employed to control the traverse motion of the ring and traveler across the barrel 8 and to wind the yarn evenly on the yarn support.

In the outside edge of the flange I is a smooth peripheral groove 9 extending completely around the circumference of the flange. The groove 9 may be positioned above, below, or at the center of the flange 7. As shown, the groove 9 is positioned above the center of the flange. Cut into the upper plane surface la of the flange l are a series of smooth grooves which are positioned tangentially to the barrel 8 and communicate with the peripheral groove G as shown particularly in Figure 3. On the lower surface lb of the flange l are shallow slots ii disposed circumferentially about the flange Ti. These shallow slots serve as means for severing and engaging the yarn when it is held against them at a time when the yarn support is rotating at high speed. The flange I may be attached to the barrel 8 as by screws or nails I2 or may be made integral with the barrel 8 and the upper flange if desired.

In order to apply the magazine wrap or transfer tail to our novel form of yarn support, the empty yarn support is allowed to come up to speed on the rotating spindle. Yarn coming from a suitable source such as a metier or spinning cabinet or any source of supply for winding on the yarn support is led downward, threaded through the traveler and thrown upon the rapidly rotating yarn support by the usual throw-on technique whereupon winding of the yarn on to the yarn support proceeds. At the bottom of the stroke of the traverse motion, the yarn is automatically or manually guided down into one of the slots l0 and into the peripheral groove 9,

The rapidly rotating motion of the yarn support by the spindle causes the yarn to be wound for a number of revolutions in the peripheral groove 9. The yarn is then guided upward by the guiding means into another of the slots l0 and the yarn is permitted to continue winding and twisting on the hollow shaft 8 of the yarn support to form a yarn package having an available magazine wrap or transfer tail. A means for guiding the yarn down into the peripheral groove 9 and upward again so that it winds in the usual manner is more particularly described in co-pending application S. No. 353.534.

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of our invention.

Having described our invention, what we desire to secure by Letters Patent is:

1. In a yarn support adapted to receive a transfer tail, the combination of a base flange on said yarn support having a peripheral groove therein and a plurality of grooves on the inner surface of said flange tangential to the normally circular path of the yarn and communicating with said peripheral groove, at least one of said grooves being directed clockwise to said circular path and at least one being directed anticlockwise.

2. In a yarn support adapted to receive a transfer tail, the combination of a base flange on said yarn support having a peripheral groove therein, a plurality of grooves on the inner surface of said flange tangential to the normally circular path ,of the yarn and communicating with-said peripheral groove, at least one of said grooves being directed clockwise to said circular path and at least one being directed anti-clockwise, and at least one short radial groove on the outer surface of the flange to facilitate severance of the yarn.
